Bluetooth: mgmt: Add idle_timeout to configurable system parameters

While the configurable system parameters allow controlling the SNIFF
mode parameters, they do not include the idle_timeout parameter
responsible for enabling SNIFF mode.

Add the idle_timeout parameter to allow controlling the idle timeout
of BR/EDR connections.
